UFC 163 takes place Aug. 3 at HSBC Arena in Rio de Janeiro. Barroso vs. Oliveira is expected to be part of the Facebook-streamed preliminary card, which precede additional prelims on FX and a pay-per-view main card.

Barroso enters the UFC with three straight wins and 12 victories in his past 13 fights. “Bodao’s” sole defeat during the streak came to Russian fighter Baga Agaev. In April he submitted Simao Melo da Silva at a regional show in his native Brazil. It was his 14th stoppage in 15 career wins.

Oliveira returns to action for the first time since UFC 142 in early 2012, when he suffered a submission loss to heavyweight Gabriel Gonzaga in his promotional debut. Prior to that, the Brazilian striker had posted eight knockouts in an undefeated start to his career. Recently injuries have slowed his return to the cage.
